Cloud Computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid.
Cloud computing is a paradigm shift following the shift from mainframe to client–server in the early 1980s. Details are abstracted from the users, who no longer have need for expertise in, or control over, the technology infrastructure "in the cloud" that supports them. Cloud computing describes a new supplement, consumption, and delivery model for IT services based on the Internet, and it typically involves over-the-Internet provision of dynamically scalable and often virtualized resources. It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet.
The term "cloud" is used as a metaphor for the Internet, based on the cloud drawing used in the past to represent the telephone network, and later to depict the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. Typical cloud computing providers deliver common business applications online that are accessed from another Web service or software like a Web browser, while the software and data are stored on servers.
Most cloud computing infrastructures consist of services delivered through common centers and built on servers. Clouds often appear as single points of access for all consumers' computing needs. Commercial offerings are generally expected to meet quality of service (QoS) requirements of customers, and typically include SLAs. The major cloud service providers include Microsoft, Salesforce, Skytap, Amazon and Google.

What is a Hybrid server
KnownHost's Hybrid Servers are designed using Custom Built Enterprise class hardware featuring Dual CPU Dual Core Opterons with RAID 10 configurations and the Virtualization technology Virtuozzo. Each Hybrid Server has a guaranteed amount of RAM, Bandwidth and Disk Space and is fully isolated from other users on the machine.
A Hybrid server essentially is a high-end VPS on a machine with other hybrid servers but the CPU share you get is much higher as we only put a mix of 4-8 plans per machine. All servers are capped at around 80% to allow for maximum performance and growth.
Top 5 Reason why a Hybrid Server is right for you
Want to know why a Virtual Private Server is better then a shared hosting solution? Read the five biggest advantages below:
1. Reliability
* With the use of a KnownHost VPS you will experience reliability at its best. With extensive technical knowledge and experience you can expect reliable VPS’s with industry leading uptime.
2. Flexibility
* Ability to customize system configuration, install any applications and server wide software to fit your sites needs. Full root level access and almost complete control over the system configuration brings hosting to next level without the dedicated server’s price tag
3. Performance
* With custom built servers you will benefit from Enterprise class hardware with RAID-10 storage for redundancy. No factory built servers here!
4. Easy-to-use GUI/Complete control over the VPS
* This is a browser based GUI tool which allows you to restart, troubleshoot, and restore your own VPS without the help of your provider. You can also restart the core server components such as Apache, FTP, and DNS; even deploy a fresh OS with your former VPS account's data mounted to the new OS. This is all functionality free with all VPS packages. Restore a backup on the fly if you need to reinstall due to some sort of attack.
5. Security/Upgrades
* We manage the physical servers and assure their properly secured. Individual VPS's are secured out of the box. We can also assist with further server security if requested.
6. Dynamic
* When using a VPS, you have the peace of mind to know your performance will never be lacking. As you grow along with your web traffic, the VPS will adapt as needed with the use of the Virtuozzo technology. Upgrading to a higher resource VPS is simple with no downtime.[1]
